Instructions

Here are the easy step-by-step instructions to make this baked sliders recipe with beef & cheese. It only takes a few minutes to prep the ingredients and assemble them. If you have caramelized onions already made, these sliders are a quick & fast recipe. In under 30 minutes, this slide recipe is hot, melty, and ready to eat.

Make the Caramelized Onions

To make the caramelized onions, you want to cook slices low and slow in butter. This can take about 30-45 minutes, depending on how sweet & deep brown you want them. Here are the easy steps for learning how to make caramelized onions. Once they are done, let them cool and it is time to start making the sliders.

How to Assemble the Sliders

Before you begin preparing everything, preheat the oven to 375°. Next, gather all the ingredients. The steps for making these include slicing the rolls, piling the ingredients inside, and topping the sandwiches.

Grab your best bread knife (serrated knife). Slice the Hawaiian rolls in half horizontally. Try your best to make the tops and bottoms of equal thickness. Place the bottoms in a 7x11 rimmed baking dish. Let the tops rest on the side.

Next, the condiments will be spread on the bottom half of the rolls. I recommend using horseradish cream. Or combine fresh horseradish with sour cream to make your own. As an alternative, use dijon or yellow mustard. (my kids prefer mustard so I do ½ & ½ sometimes)

Now add the tops of the rolls to cover up the cheese slices. Once the sliders are assembled, it is time to make the basting sauce.

Basting & Baking Beef & Cheddar Sliders

These meaty sliders have an amazing dijon & butter topping. It bakes into those soft rolls for so much added yumminess. Do not skip this step!

To make the basting sauce, just whisk together a few savory items. In a small microwave-safe bowl, melt the salted butter. Whisk in the dijon mustard and Worcestershire sauce. Using a pastry brush, coat the tops of all the rolls with the sauce.

Finally, sprinkle on some paprika and then they are ready for baking. Cover the baking dish with foil. Place the covered baking dish on a rack in the center of the oven. Bake for 15-20 minutes.

Hint: This keeps the rolls soft while cooking. If you want crispy tops, remove the foil for the final 5 minutes of baking.

You know the beef and cheddar sliders are ready when the cheese is melted. The rolls will be glistening with buttery tops that are soft & not soggy. Carefully, remove them from the oven using oven mitts. Let them sit for a few minutes.

CAUTION: the cheese may be molten hot! Letting the rolls sit for a minute not only allows the cheese to cool a bit but also helps the rolls stay intact when you cut them.

How to Serve Sliders

Once they are set up, use a knife to cut between the rolls. Use a spatula to remove a slider one at a time to enjoy. The small oven-baked slider rolls will be plump and filled with all that beefy cheesy goodness.

If these are for a party, slice them and leave them in the baking dish. Or move them to a platter. When hosting guests, I like serving these with other tasty small bites such as some Hot Honey Lemon Pepper Wings and Air-Fried Frozen Coconut Shrimp.

Substitutions

If you have dietary or allergy requirements, here are a few changes you can make. This recipe is already nut-free. But if you want gluten-free or dairy-free, these alternatives work well with this recipe.

• Slider Rolls - use gluten-free buns or rolls to make gluten-free sliders.
• Worcestershire Sauce - if you don't have any on hand, try one of my recommended substitutes for Worcestershire sauce.
• Caramelized Onions - I highly recommend you use these but if you are short on time, use thinly sliced raw onion instead.
• Cheddar - I use sharp but you can use mild or medium cheddar.

For a dairy-free slider recipe, instead of regular cheddar use your favorite dairy-free cheese. Also, swap out the butter for margarine.

Variations

Here are some small changes for this recipe to better suit your taste, guests, or occasion. These variations work well to alter this recipe for beef & cheddar sliders without changing it too much.

• Extra Spicy - add a layer of spicy jalapeno or pepperoncini peppers.
• Cheesy - instead of cheddar use your favorite sliced cheese or use two kinds for a cheese lover delight.
• Mild/Kid-friendly - use yellow mustard instead of the spicy horseradish sauce.

Equipment

A baking dish, pastry brush, and a really good bread knife are important for making these sliders. Here are my recommendations for a few great bread knife choices and some other tools every kitchen needs.

Storage

To store leftover homemade sliders, place them in an air-tight container or top the baking dish with foil again. Store in the refrigerator for up to 3 days. Reheat in the oven, toaster oven, or microwave.

I do not recommend freezing these sliders either before or after baking. The bread will not hold up well in the freezer with the tomatoes and pesto. Defrosting will change the texture and result in a soggy texture.
